Boronic esters are versatile synthetic intermediates for the preparation of a wide range of organic molecules. The development of new methods to create C-B bonds in an efficient, inexpensive, and environmentally friendly way is therefore an important challenge in organic chemistry. Traditionally, the methods to form C-B bonds have mostly been based on the electrophilic nature of boron. Recently, copper-catalyzed borylations have emerged as a new source of nucleophilic boron. The lower price and toxicity of copper versus other transition metals and the unique reactivity of the boryl-copper intermediates make these processes particularly attractive. We have used boryl-copper species to synthesize a broad variety of useful synthetic intermediates such as 1,4-diols, trisubstituted alkenes, dibenzylic derivatives, aminoboronates, allenes and functionalized small rings. Some of these results will be presented in this talk.
